BUR-CARRIER FOR GAMING-MACHINES.

Specification ofLetters Patent.

Patented May 23, 1916.

Application filed January 11, 1916. Serial No. 71,571.

To all whom it may concern Be it known that we, WRIGHT Pnns'rwion andERNEST PRESTWICH, citizens of the United States, and residentsofvLawrence,

county of Essex, State of Massachusetts,

have invented an Improvement in Bur-Carriers for Carding-Machines, ofwhich the following description, in connection with the accompanyingdrawing,'is a specification, like characters onthe drawing'representinglike parts.

This invention relates toimprovements in bur carriers for cardingmachines and the like and the object thereof is to provide a bur carrierattachment which may be readily associated with standard cardingmachines or the like and in which the positions of the clearers for thebur pans may be'more accurately positioned.

The invention" disclosed herein comprises an improvement upon our priorPatent No. 924,379granted June 8, 1909 which shows a carding machineequippedwith a series of bur pans with independently operated carrierand clearers for each of the pans, the traverse. shafts for said pansbeing supported upon brackets'secured tothe ends of the cardingmachineframe and adjustable vertically in respect thereto.

In the present invention the same type of 'tra\ 'erse shafts andclearers for the bur. pans may be used but means are provided to enabletwo of the traverse shafts to actuate simultaneously clearers for threeor more pans, thus reducing the expense ofinstallation and economi'zingthe cost of operation of the machine.

Another feature of the invention resides in so constructing thesupporting means for the traverse shafts as to provide means foradjusting the same both vertically and laterally thereby permitting theclearers to be positioned more readily and more accurately in respect tothe pans.

Another feature of the invention consists in providing;adjustablefrictional means for controlling the action of the members for raisingthe clearers to inoperative position. Other features of the inventionwill more fully appear from the following description and theaccompanying drawings and will be pointed out in the annexed claims.

In the drawingszFigure 1 is a side elevation of a portion of a worstedcard showing the bur rolls and pans with a preferred embodiment of thepresent invention applied thereto, Fig. 2 is an enlarged transversedetail view showing the bur clearers and the mechanism for operating thesame. Fig. 3 is a vertical transverse sectional view through ,one oftheftraverse shafts and the carriage for the clearers showing one of theclearers in elevation and illustrating the frictional device forcontrolling the position of the olearers. Fig.4 is a side elevation ofone of the brackets for support ing the traverse roll and a portion ofits supporting standard, and, Fig. 5 is a detail view of one of theadjustable hunters for positioning the clearers.

Worsted cards are generally provided with a series of bur rolls inadvance of the carding mechanism so arranged as to remove the burs fromthe material being carded and dischargethe same into pans, which extendtransversely across the machine, the pans having open ends from whichthe burs are removed by an attendant by means of a long rake or scraper.When the material carded is dirty these burs collect Lrapidly in thepans and a large portion of the time of the attendant is required tokeep the pans clear, particularly ifheis looking after a number of cardsBy the present invention automatic clearers are provided which dischargethe burs from all of the pans preferably into a common chute whichdelivers them into a suitable receptacle, thus freeing' the attendantfrom this amount. of labor so that fewer attendants are required.

The drawings illustrate the bur cleaning end of a standard cardcomprising end frames 1, 2 having suitable journals for the rotatingmechanism which includes the bur cylinder 3, the licker-in cylinders 4,5, the top dividers 6, 7, the bottom divider 8, the feed stripper 9, thebur rolls 10, 11, 12, 13 and 14, shown as arranged in two groups, andcorresponding bur pans 15, 16, 17, 18, 19 which may be and are ofsubstantially well known construction in worsted cards and operated inthe usual manner, the burs being deposited by the bur wheels in the burpans.

For clearness of illustration a large porticn of the driving mechanismhas been omitted but it will be understood that the same is of .thecharacter usual in worsted cards of this type.

bur cylinders in such a manner that the burs of the clearer blades beingactuated simultaneously by finger members connected by gears. Asillustrated herein the depending plate 51 of thecarriage is providedwith studs 56 upon which are pivoted the hubs 58 59 of the clearerraising fingers 60-'61 the hubs 58, 59 being provided withintermeshinggears 62, 63adapted simultaneously to raise the clearerblades when actuated in one. direction and to permit the clearer bladesto drop by gravity into a substantially vertical position when actuatedin the opposite direction.

One of the hubs 58 or 59 is provided with an upwardly extending arm 64adapted to engage a suitable bunter positioned in its path of traveladjacent the respective ends of the traverse shaft.

In order to maintain the clearers in elevated position during the returnstroke frictional' means are preferably provided-for retaining theclearer actuating members in any desired elevation. In the preferredembodiment of the invention disclosed herein this is accomplished byproviding the studs 56, upon which the hubs 58 or 59 are mounted, withextensions 65 and surrounding'said studs with helical springs 66 adaptedto bear at one end against the hub and at the other upon the base ofwinged nuts 67 which may be adjusted to produce a sufficient compressionupon the springs 66 to give the desired amount of friction.

The hunters for controlling the members which actuatethe clearersarepreferably in the form of brackets having adjustments to permitvertical and lateral positioning. The hunters for the end. carriages 29,30 may conveniently be carried upon the brackets 34: which support thetraverse rolls. As illustrated in Fig. 4 of the drawing the bracket isprovided with a'downward extension 68 to which a plate 69'is connectedby bolt and slot connections 70, 71 permitting vertical adjustment, thelower end of the plate 69 being offset to provide a horizontal portion72 to which is connected the hunter 7 3 which may be in the form of aplate having a longitudinal slot 74: adapted to receive a bolt 7 5 bymeans of which the plate 7 3 may be adjusta-bly connected to the plate69. It will thus be observed that the hunter 7 3 may be positioned bothvertically and laterally to cotiperate properly with the arm 64: of theclearer actuating member at either end of the machine.

In order to provide for the actuation of the intermediate clearer acurved plate 74 may conveniently be secured to either of the brackets 34the end of the hunter 74 extending in the path of the arm 64 of theactuator upon the intermediate carriage.

Where but two of the bur pans are provided as at the left end of theportion of the machine shown in the drawing, the carriages mayconveniently be connected together by a suitable bridge so that thecarriages will move in unison and both carriages may if desired beoperated by a single traverse thereafter as will be readily understood.

It will be understood that the embodiment of our invention illustratedin'the accompanying drawings is illustrative merely and that theinvention may be embodied in other forms within the meaning and scope ofthe following claims.
